From d241dee4dda34d36a9e94468ae9dcfe07c6ac060 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Tue, 3 Mar 2020 12:15:06 +0100 Subject: Linux: Clean up preadv, pwritev system call names The names __NR_preadv64, __NR_pwritev64 appear to be a glibc invention. With the built-in tables, __NR_preadv and __NR_pwritev are always defined.
